Description

Technical Field

[0001] This invention relates to the field of woven bag processing technology, and more specifically, to a woven bag processing equipment and its processing technology. Background Technology

[0002] Woven bags are bags made primarily of plastic through a weaving process. They are typically made of plastic materials such as polypropylene and polyethylene. The manufacturing process involves drawing plastic raw materials into threads, then weaving these threads into a fabric using weaving equipment, and finally cutting and sewing them to create the bags.

[0003] The sewing process includes the sewing of the woven bag opening, which is the process of sewing the edge of the woven bag opening. The purpose is to ensure that the opening of the woven bag will not easily break or loosen after it is filled with goods, to prevent leakage of goods, and to maintain the stability of the bag shape, so that the opening shape of the woven bag remains regular, making it easy to fill and empty goods.

[0004] In existing processes for sewing the opening edges of woven bags, machine sewing is the most common method, providing a stable stitching effect. However, in practice, manual sewing is usually performed. Workers need to fold the opening edge of the woven bag inwards with both hands, pressing it down to maintain stability, and then move the opening edge towards the sewing machine needle to sew it closed. However, manual movement of the folded bag is difficult to maintain stability due to the pressure and movement from both hands, easily causing changes in the fold size. This results in misaligned opening shapes, increased defect rates, and reduced stitching quality. Therefore, we propose a woven bag processing equipment and its processing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a woven bag processing equipment and its processing technology to solve the technical problem that it is difficult to ensure the stability of the woven bag movement in the manual operation of sewing the opening edge of the woven bag, which easily causes the size of the folded edge to change, increases the defect rate, and reduces the sewing effect.

[0007] The sewing machine body includes an operating table;

[0008] The clamping assembly includes two clamping plates disposed on the top surface of the operating table, used to clamp the woven bag after the opening edge is folded;

[0009] The spreading component is located at the bottom of the operating table and is used to spread open the opening of the woven bag;

[0012] A clamping channel is formed between the bottom of the clamping plate and the top surface of the support plate;

[0013] The bottom surface of the support plate is connected to a slide rail, and the other end of the slide rail is connected to a fan-shaped guide plate;

[0014] The spreading assembly includes multiple sliders sleeved on the slide rail, with a slide rod connected to the bottom of each slider. The top surface of the slide rod has a groove that matches the bottom structure of the slide rail. The slide rod slides in cooperation with the slide rail through the multiple sliders and the groove.

[0015] A support head is provided at the end of the slide rod, and a rotating wheel is rotatably connected inside the support head, with the outer circumference of the rotating wheel extending beyond the outer circumference of the support head.

[0016] A baffle is connected to the side wall of the slide bar, and a rack is connected to the side wall of the baffle. A motor is installed on the side wall of the sewing machine body, and a gear is installed at the output end of the motor. The output end of the gear meshes with the rack.

[0017] Preferably, the outer circumferential wall of the fan-shaped guide plate is provided with a groove, and multiple rotating columns are rotatably connected in the groove of the fan-shaped guide plate.

[0018] Preferably, the top surface of the clamping plate is provided with a limiting groove, and the rotating column is movably connected within the limiting groove.

[0019] Preferably, the clamping plate has an arc-shaped plate structure, and the entrance of the clamping channel has an arc-shaped opening.

[0020] Preferably, the clamping plate has a square groove at the bottom, and a plurality of arrayed hemispherical grooves are formed on the bottom surface of the square groove. A sphere is placed in the hemispherical groove, and a fixed ball frame is connected to the bottom surface of the square groove. The sphere is movably connected in the hemispherical groove, and the bottom of the sphere extends out of the bottom of the fixed ball frame and contacts the top surface of the support plate.

[0021] Preferably, the transmission assembly includes a motor plate disposed above the rack, a second motor disposed on the top surface of the motor plate, a second gear disposed at the output end of the second motor, a third gear meshing with the output end of the second gear, a fourth gear coaxially connected to the third gear, a fifth gear meshing with the output end of the fourth gear, a sixth gear meshing with the output end of the fifth gear, and the sixth gear coaxially connected to the rotating wheel.

[0022] Preferably, the sidewall of the baffle is rotatably connected to gears three, four, five and six.

[0023] Preferably, the support head is a semi-circular structure, and the baffle is a combination of a semi-circular structure and a long strip structure that match the shape of the support head and the sliding rod.

[0024] Preferably, the outer circumferential wall of the rotor is configured with an alternating concave-convex structure made of rubber.

[0025] Preferably, the processing technology of the woven bag processing equipment includes the following steps:

[0026] S1. Pre-treatment operation: Fold the edges of the opening of the woven bag inward.

[0027] S2. Clamping operation: Insert the open edge of the folded woven bag into the clamping channel from below the clamping plate. At this time, the spring exerts a downward elastic force on the fixing frame, causing the fixing frame to press down into the limiting groove on the top surface of the clamping plate in conjunction with the rotating column at the bottom of the pressing frame. This causes the clamping plate to press the open edge of the woven bag down onto the top surface of the support plate, keeping the open edge of the woven bag folded.

[0028] S3. Insertion operation: After the two clamping plates clamp the opening edge of the woven bag, insert the opening edges on both sides of the woven bag onto the fan-shaped guide plate and the outer circumference of the opening. The opening edge at the bottom of the woven bag is placed between the slide bar and the side of the baffle.

[0029] S4. Spreading operation: When the motor is working, it drives the gear to rotate, which in turn drives the rack to move, causing the slide bar to slide on the slide rail. The spreading head at the end of the slide bar moves away from the fan-shaped guide plate. At this time, the distance between the spreading head and the fan-shaped guide plate gradually increases until the opening edge of the woven bag is spread open.

[0030] S5. Sewing Operation: After the opening edge of the woven bag is stretched open, the sewing machine body sews the opening edge of the woven bag to ensure a firm folded edge. Simultaneously, motor two drives gears two, three, four, five, and six to rotate. Gear six drives a coaxially connected roller to rotate. The concave-convex structure on the outer wall of the roller contacts the inner wall of the opening edge of the woven bag. Through rotational friction, the opening edge of the woven bag moves along the clamping channel. In conjunction with multiple rolling balls at the bottom of the clamping plate of the clamping channel, the opening edge of the woven bag moves smoothly and continuously through the sewing machine body to sew the opening edge of the woven bag until the loop is closed and the woven bag is removed.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention uses a clamping component to hold the opening edge of the woven bag and a spreading component to spread the opening edge of the woven bag to prevent wrinkles. A transmission component moves the opening edge of the woven bag, and the sewing machine body sews it. This eliminates the need for workers to directly press and move the opening edge of the woven bag by hand, which can easily lead to misalignment. The clamping component, spreading component, and transmission component can replace manual operation, ensuring the stability of the opening edge of the woven bag during folding and movement, improving the sewing effect, and reducing the defect rate.

[0033] 2. This invention also designs a clamping plate with an arc-shaped structure, making the entrance of the clamping channel have an arc-shaped opening. This facilitates inserting the open edge of the folded woven bag into the clamping channel. After being inserted, the spring exerts a downward elastic force on the fixing frame, causing the fixing frame to press down into the limiting groove on the top surface of the clamping plate in conjunction with the rotating column at the bottom of the pressing frame. This causes the clamping plate to press the open edge of the woven bag down onto the top surface of the support plate, maintaining the folded state of the open edge of the woven bag. This helps to prevent the open edge of the woven bag from becoming disordered during subsequent sewing, further improving the sewing effect.

[0034] 3. This invention further utilizes two clamping plates to clamp the opening edge of the woven bag. The opening edges on both sides of the woven bag are then fitted onto the outer circumference of the fan-shaped guide plate and the opening head. The opening edge at the bottom of the woven bag is positioned between the slide rod and the side of the baffle. When the motor operates, it drives the gear to rotate, further moving the rack and pinion, causing the slide rod to slide on the slide rail. The opening head at the end of the slide rod moves away from the fan-shaped guide plate. At this point, the distance between the opening head and the fan-shaped guide plate gradually increases until the opening edge of the woven bag is opened. By designing the opening head and fan-shaped guide plate to open the opening edge of the woven bag, and cooperating with the two clamping plates to clamp the opening edge, the folded state of the woven bag's opening edge is further positioned and fixed, preventing misalignment and ensuring the stability of the folded state of the woven bag's opening edge, thus improving the subsequent sewing effect.

[0035] 4. In addition, the present invention also uses motor 2 to drive gears 2, 3, 4, 5 and 6 to rotate. Gear 6 drives a coaxially connected wheel to rotate. The concave-convex structure on the outer side wall of the wheel contacts the inner side wall of the opening edge of the woven bag, increasing the friction with the woven bag. Through rotational friction, the opening edge of the woven bag moves along the clamping channel. In addition, multiple rolling balls at the bottom of the clamping plate of the clamping channel roll on the top surface of the opening edge of the woven bag, making the movement of the opening edge of the woven bag smoother. This further improves the smoothness and stability of the movement of the opening edge of the woven bag and ensures the sewing effect. Attached Figure Description

[0052] like Figures 1 to 10 As shown, the present invention relates to a woven bag processing equipment, including a sewing machine body 1, a clamping assembly 2, a spreading assembly 3 and a transmission assembly 4;

[0053] In an embodiment of the present invention, the sewing machine body 1 includes an operating table 101; the clamping component 2 includes two clamping plates 201 disposed on the top surface of the operating table 101 for clamping the folded edge of the woven bag opening; the spreading component 3 is disposed at the bottom of the operating table 101 for spreading the opening of the woven bag; the transmission component 4 is disposed on the side wall of the spreading component 3 for transmitting the woven bag opening edge to the sewing point of the sewing machine body 1; by designing the clamping component 2 to clamp the folded edge of the woven bag opening, the folded state of the woven bag opening edge is ensured, and the spreading component 3 is used to spread the woven bag opening edge to prevent wrinkles. The transmission component 4 is used to move the woven bag opening edge, and the sewing is performed by the sewing machine body 1. It eliminates the need for the operator to directly press and move the woven bag opening edge by hand, which is prone to errors. The clamping component 2, spreading component 3 and transmission component 4 can replace manual operation, ensuring the stability of the woven bag opening edge during folding and movement, improving the sewing effect and reducing the defect rate.

[0054] In an embodiment of the present invention, a fixing plate 202 is rotatably connected to the top surface of the clamping plate 201, a support plate 203 is connected to the bottom of the fixing plate 202, a pressing frame 204 is rotatably connected to the side wall of the fixing plate 202, a rotating column 205 is rotatably connected to the bottom of the pressing frame 204, a limiting groove 208 is provided on the top surface of the clamping plate 201, the rotating column 205 is movably connected within the limiting groove 208, a fixing frame 206 is connected to the top surface of the pressing frame 204, and a spring 207 is provided on the top surface of the fixing frame 206; a clamping channel is formed between the bottom of the clamping plate 201 and the top surface of the support plate 203, the clamping plate 201 is an arc-shaped plate structure, and the entrance of the clamping channel is an arc-shaped opening. The bottom surface of the support plate 203 is connected to a slide rail 209, and the other end of the slide rail 209 is connected to a fan-shaped guide plate 210. By designing the clamping plate 201 with an arc-shaped plate structure, the entrance of the clamping channel is made to have an arc-shaped opening, which makes it easy to insert the opening edge of the folded woven bag into the clamping channel. After being inserted into the clamping channel, the spring 207 generates a downward elastic force on the fixing frame 206, so that the fixing frame 206 cooperates with the rotating column 205 at the bottom of the pressing frame 204 to press down into the limiting groove 208 on the top surface of the clamping plate 201, so that the clamping plate 201 presses the opening edge of the woven bag down onto the top surface of the support plate 203, keeping the opening edge of the woven bag in a folded state.

[0055] In an embodiment of the present invention, the spreading component 3 includes a plurality of sliders 301 sleeved on the slide rail 209. The bottom of the sliders 301 is connected to a slide rod 302. The top surface of the slide rod 302 is provided with a groove 303 that matches the bottom structure of the slide rail 209. The slide rod 302 slides in cooperation with the slide rail 209 through the plurality of sliders 301 and the groove 303. A support head 304 is provided at the end of the slide bar 302. A rotating wheel 305 is rotatably connected inside the support head 304, and the outer circumference of the rotating wheel 305 extends beyond the outer circumference of the support head 304. The outer circumference of the rotating wheel 305 is made of rubber with an alternating concave-convex structure. The rubber material can reduce damage to the woven bag, and the alternating concave-convex structure increases the friction with the woven bag, improving the transmission effect on the woven bag. A baffle 306 is connected to the side wall of the slide bar 302, and a rack 307 is connected to the side wall of the baffle 306. A motor 308 is provided on the side wall of the sewing machine body 1. A gear 309 is provided at the output end of the motor 308, and the output end of the gear 309 meshes with the rack 307. After the two clamping plates 201 complete the clamping operation on the opening edge of the woven bag, the opening edges on both sides of the woven bag are fitted onto the fan-shaped guide plate 210 and the support head. On the outer circumference of the head 304, the opening edge of the woven bag at the bottom is positioned between the slide bar 302 and the side of the baffle 306. The motor 308 drives the gear 309 to rotate, which in turn drives the rack 307 to move, causing the slide bar 302 to slide on the slide rail 209. The supporting head 304 at the end of the slide bar 302 moves away from the fan-shaped guide plate 210. At this time, the distance between the supporting head 304 and the fan-shaped guide plate 210 gradually increases until the opening edge of the woven bag is opened. By designing the supporting head 304 and the fan-shaped guide plate 210 to open the opening edge of the woven bag, and cooperating with the two clamping plates 201 to clamp the opening edge of the woven bag, the folded state of the opening edge of the woven bag is positioned and fixed, making it difficult for it to become disordered. This ensures the stability of the folded state of the opening edge of the woven bag and improves the subsequent sewing effect.

[0056] In another embodiment of the present invention, a groove is provided on the outer circumference of the fan-shaped guide plate 210, and a plurality of rotating columns 211 are rotatably connected in the groove of the fan-shaped guide plate 210. By rotating the rotating columns 211, it is beneficial for the edge of the woven bag opening to move on the outer circumference of the fan-shaped guide plate 210.

[0057] In another embodiment of the present invention, a square groove 212 is provided at the bottom of the clamping plate 201, and a plurality of arrayed hemispherical grooves 213 are provided on the bottom surface of the square groove 212. A sphere 214 is provided in the hemispherical groove 213, and a fixed ball frame 215 is connected to the bottom surface of the square groove 212. The sphere 214 is movably connected in the hemispherical groove 213, and the bottom of the sphere 214 extends out of the bottom of the fixed ball frame 215 and contacts the top surface of the support plate 203.

[0058] Transmission assembly 4 includes a motor plate 401 disposed above rack 307. A second motor 402 is disposed on the top surface of motor plate 401. A second gear 403 is disposed at the output end of motor 402. A third gear 404 is meshed with the output end of gear 403. A fourth gear 405 is coaxially connected to gear 404. A fifth gear 406 is meshed with the output end of gear 405. A sixth gear 407 is meshed with the output end of gear 406. A rotating wheel 305 is coaxially connected to gear 307. Gears 304, 405, 506, and 607 are rotatably connected to the side wall of baffle 306. The transmission assembly 4 is driven by motor 402. The operation drives gears 2 (403), 3 (404), 4 (405), 5 (406), and 6 (407) to rotate. Gear 6 (407) drives the coaxially connected rotating wheel 305 to rotate. The concave-convex structure on the outer wall of the rotating wheel 305 contacts the inner wall of the opening edge of the woven bag. Through rotational friction, the opening edge of the woven bag moves along the clamping channel. In conjunction with the multiple rolling balls 214 at the bottom of the clamping plate 201 of the clamping channel, the balls roll on the top surface of the opening edge of the woven bag, making the movement of the opening edge of the woven bag smoother and further improving the stability of the opening edge during movement, thus ensuring the sewing effect.

[0059] In another embodiment of the present invention, the support head 304 is a semi-circular structure, and the baffle 306 is a combination of a semi-circular structure and a long strip structure that matches the shape of the support head 304 and the slide bar 302. The baffle 306 can ensure that the opening edge of the woven bag is located in the space below the slide bar 302 and to the side of the baffle 306, and prevent the opening edge of the woven bag from entering the transmission assembly 4.

[0060] Working Principle: This embodiment provides a processing technology for a woven bag processing equipment, including the following steps: First, the opening edge of the woven bag is folded inward. Then, the folded opening edge of the woven bag is inserted into the clamping channel from below the clamping plate 201. At this time, the spring 207 exerts a downward elastic force on the fixing frame 206, causing the fixing frame 206 to cooperate with the rotating column 205 at the bottom of the pressing frame 204 to press down into the limiting groove 208 on the top surface of the clamping plate 201, so that the clamping plate 201 clamps the opening edge of the woven bag. The edge of the bag is pressed against the top surface of the support plate 203 to keep the folded edge of the woven bag folded. Then, after the two clamping plates 201 clamp the opening edge of the woven bag, the opening edges on both sides of the woven bag are placed on the outer circumference of the fan-shaped guide plate 210 and the opening head 304. The opening edge at the bottom of the woven bag is positioned between the slide rod 302 and the side of the baffle 306. Furthermore, the motor 308 drives the gear 309 to rotate, which in turn drives the rack 307 to move, so that the slide rod 302 moves along the slide rail 209. As the slide bar 302 slides upwards, the support head 304 at its end moves away from the fan-shaped guide plate 210. At this time, the distance between the support head 304 and the fan-shaped guide plate 210 gradually increases until the opening edge of the woven bag is opened. Finally, after the opening edge of the woven bag is opened, the sewing machine body 1 works to sew the opening edge of the woven bag, ensuring a secure folded edge. Simultaneously, the motor 402 drives gears 403, 404, 405, 406, and 407. 7. The gear 6 407 drives the coaxially connected rotary wheel 305 to rotate. The concave-convex structure of the outer wall of the rotary wheel 305 contacts the inner wall of the opening edge of the woven bag. Through rotational friction, the opening edge of the woven bag moves along the clamping channel. In conjunction with the multiple rolling balls 214 at the bottom of the clamping plate 201 of the clamping channel, they roll on the top surface of the opening edge of the woven bag, making the opening edge of the woven bag move smoothly. It can continuously sew the opening edge of the woven bag through the sewing machine body 1 until the closed loop is completed and the woven bag is removed.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.

The woven bag processing equipment according to claim 7, characterized in that, The support head (304) has a semi-circular structure, and the baffle (306) is a combination of a semi-circular structure and a long strip structure that matches the shape of the support head (304) and the slide bar (302).

9. A woven bag processing equipment according to claim 8, characterized in that, The outer circumference of the wheel (305) is made of rubber with an alternating concave and convex structure.

10. The processing technology of the woven bag processing equipment according to claim 9, characterized in that, Includes the following steps: S1. Pre-treatment operation: Fold the edges of the opening of the woven bag inward. S2. Clamping operation: Insert the open edge of the folded woven bag into the clamping channel from below the clamping plate (201). At this time, the spring (207) generates a downward elastic force on the fixing frame (206), causing the fixing frame (206) to cooperate with the rotating column (205) at the bottom of the pressing frame (204) to press down into the limiting groove (208) on the top surface of the clamping plate (201), so that the clamping plate (201) presses the open edge of the woven bag down onto the top surface of the support plate (203), keeping the open edge of the woven bag in a folded state. S3, Insertion operation: After the two clamping plates (201) complete the clamping operation on the opening edge of the woven bag, the opening edges on both sides of the woven bag are inserted onto the circumferential outer wall of the fan-shaped guide plate (210) and the opening head (304). The opening edge at the bottom of the woven bag is placed between the slide bar (302) and the side of the baffle (306). S4. Opening operation: Motor 1 (308) works to drive gear 1 (309) to rotate, which in turn drives rack (307) to move, so that slide rod (302) slides on slide rail (209). The opening head (304) at the end of slide rod (302) moves away from the fan-shaped guide plate (210). At this time, the distance between the opening head (304) and the fan-shaped guide plate (210) gradually increases until the opening edge of the woven bag is opened. S5. Sewing operation: After the opening edge of the woven bag is opened, the sewing machine body (1) works to sew the opening edge of the woven bag, so that the folded opening edge is sewn firmly. At the same time, the motor (402) works to drive the gears (403), (404), (405), (406), and (407) to rotate. The gear (407) drives the coaxially connected wheel (305) to rotate. The concave-convex interlocking structure of the outer wall of the wheel (305) contacts the inner wall of the opening edge of the woven bag. Through rotational friction, the opening edge of the woven bag moves along the clamping channel. In conjunction with the multiple rolling balls (214) at the bottom of the clamping plate (201) of the clamping channel, they roll on the top surface of the opening edge of the woven bag, so that the opening edge of the woven bag moves smoothly and can be continuously sewn by the sewing machine body (1) until the closed loop is completed and the woven bag is removed.
